CVE-2024-36946

Summary

In the Linux kernel, the following vulnerability has been resolved:

phonet: fix rtm_phonet_notify() skb allocation

fill_route() stores three components in the skb:

  • struct rtmsg
  • RTA_DST (u8)
  • RTA_OIF (u32)

Therefore, rtm_phonet_notify() should use

NLMSG_ALIGN(sizeof(struct rtmsg)) + nla_total_size(1) + nla_total_size(4)
